\pgfimage[width=0.5\textheight]{Grafiken/Linear}
\end{center}

\begin{itemize}
  \item Linear model
  \item Difficult to express nonlinearities
  \item 1+1 $\neq$ 2
  \item Adding people to project $\neq$ Complete project faster
\end{itemize}

\begin{alertblock}<2->{Scaling Fallacy}
Large systems are like small systems, just bigger
